This invention comprises'generally a casing indicated at 1 which ishollow to provide space for a 250; spur gear 2 rigidly secured to ashaft 3 extending transversely of the casing and journallecl in the sidewalls 4 and 5 thereof. Ihe shaft extends through the wall 4 and carriesat its end a bevel pinion 6 meshing with an arcuate segment rack '55. 7carried by the handle 8 pivoted as at 9 to an ear 10 extending laterallyfrom the wall 4 of the casing. The shaft 3 also extends through theother wall 5 with its ends engaged by a nut or other suitable means forsecuring the shaft in position relative the casing, insuring thefunctioning of the gears 2 and 6.

With particular reference to Figs. 1, 10, 11 and 12 it will be seen thatthe gear 2 meshes with the twister pinion 15 of the usual and well knowntype in that it is provided with laterally extending trunnions 16 and 17and is provided with the radial slot 18 to permit the two bights of wireforming the tie for the package to be placed at substantially the centerof the twister pinion.' Said pinion is mounted in a housing formed bytwo blocks 19 and 20, the former being provided with a recess 21 cutinfrom two adjacent sides, said recess to accommodate the toothed portionof the twister pinion. Both blocks 19 and 20 are formed with bearings 22and 23 for the trunnions 17 and16 respectively,both blocks at one endbeing formed with the mouth portions 24 and 25 leading to the slottedportions of the trunnions of the twister pinion and the slot 18 thereof.It will, of course, be understood that the mouth portions 24 and 25 areoppositely curved, or flared upwardly and downwardly as shown in Fig.12, to provide easy ingress for the wires of the tie into the twisterpinion.

As usual in constructions of this character the 5'; slot 18 ofthe pinionwill be of a dimension only slightly greater thanthe diameter of a bightof the wire tie. On the other hand, the trunnions 16 and 17 as well asthe mouth portions 24 and 25 of the pinion housing blocks, each have adimension slightly greater than twice the diameter of the wire tie, sothat when the knot shown in Fig.

13 is formed, the twist portions thereof will not bind but may slipreadily from the trunnions through the mouth portions of the twisterpinion housing. 1 i a r The blocks 19 and 20 may be secured together inany suitable mannersuch'as by a bolt passing through the opening 26 ofblock 20 and. threaded into the other block 19, registration of thetrun- 1'00 nion bearings 22 and 23 being insured by employment of thedowel pins 2'7'and 28, or the like. One or both of the blocks is securedby one or more screws such as 29 to the base plate 30 of the machine, asclearly shown in Fig. 12, and preferably the assembled blocks are setclose in a cut-out portion of the bottom wall 96 of the casing toadditionally insure retention of the pinion in operating position. 7 r

The opposite walls 4 and 5 of the casing 1 are each provided with asuitable slotway disposed in registration with the mouth portions 24 and25 and the slot of the twister pinion to permit ready entry of thebights of the tie wire as will be readily understood. The side wall 4has secured to the outer surface thereof a steel plate provided with amouth portion 36 similar to the portion 24 of the block 19, and againstthe outer side of the plate 35 is secured an L-shaped casting generallyindicated by the numeral 37,.the horizontal pore tion of whichconstitutes an anvil 38 against the upper surface of which the free endof the wire tie may be secured as by the holding dog 39. A suitable bolt40 secures the parts 35 and 37 to the side wall 4 of the casing.

The dog 39 is rigidly secured to the forward end of an oscillatory shaft41 which extends through the upper portion of the casting 37 and carriesat its rear end a lug generally indicated by the numeral 42. Through thedepending portion of this lug extends a bolt 43 passing through the wall4 of the casing and provided at its inner end with the nut 44 and aninterposedspring 45 which latter exerts a pressure tending to draw thelug 42 toward the plate 35. -This normally causes the bottom serratedsurface 46 of the dog 39 to positively engage and'grip the end of thewire tie against the anvil 3,8.

The dog 39 is provided with a tooth or projec .tion 47 adapted to engagethe latch or tripplate 48 when the dog is oscillated after the knot hasbeen tied, thereby freeing the dog from its; wire gripping position.This trip plate. is mounted 7 adjacent the anvil casting38, beingsupported taking placeat the completion of the formation on pins such as49 extending through the holes 5 0 and 51 of the latch plate, to andthrough corresponding holes in the anvil casting through correspondingholes in thesteel plate 85, and having their ends threaded as'showninFig. '5 into the side wall 40f the casing. Lightcoil springs 52 aredisposed betweenthe heads of the pins 49 and theoutersurface of the tripplate 48 to normally urge the latter against the vertical side wall ofthe anvil casting, saidtrip plate being yieldable against the tension ofthese springs during oscillation of the dog.

A rod 55 extends forwardly from the bottom portion of the lever handle 8and is adapted,

shown in Fig. 3 so that the twisted knot may be freely expelled from themachine. In other words, the parts are shown in Fig. 3 at the end of thedown stroke of handle 8 which, through the gears 7, 6 and -2,-has causedthe necessary revolutions of the twister pinion 15 to form the knot, thereleasingfand:latchingof the dog 39 of the knotf The other side of themachine is particularly illustrated in Fig. 9 but with further referenceto Figs. 1, 2 and 3, it will be seen that there is pro-' vided anothercar 60, similar to ear. 10 in that it expands laterally from the casingLand to this ear is pivoted as at 61 the lever handle 62 carrying a studroller 63 adapted to ride in the arcuate slot 64 of a lever 65 pivotedat its upper end as'at 66 to a boss 67 formed on the casing 1. The parts60, 62, 65 and 67 are disposed in parallel planes which are inclined tothe vertical plane passing through the ear 10, the purpose of thisinclination being to permit operation of the tensioning and cuttingmechanisms in more practical and efficient manners.

Figs. 1 and 3 clearly show the operation of the tensioning members ofthis machine. In other words, the lever 65 is operable to swing itslower end outwardly by virtue of the movement of the roller 63 in slot64. On the front face of the lever 65 there is formed a lug 68 at thebottom thereof and coacting with the upper surface of this lug is asecond spring pressed dog 69 pivoted as at 70 so that the loose free endof the wire tie may be gripped between said dog and said lug, the lowerportion of the dog having an extending pin '71 over which the end of thewire may be looped, as will be readily understood from the drawings. Byinclining the lever .and other parts as hereinbefore mentioned, this dog69 and the anvil lug 68 will create a pull on the held 'wire more nearlyin line with the bight which passes through the: twister pinion, therebycreating a lesser bend of 85 similar to the companion plate 35 on the.op-" posite side of the machine and against the outer surface of theplate 85 there is pivoted as at 75. a

cutter generally indicated by the numeral 76.

clearly shown in Fig. '7, with cutter edge '77, and

notch '78 to straddle the bight of the wire tie not desired tobe cut.The extreme lower. edge of the cutter is made fiat to engage thesurface. of a leaf-spring 79 secured at one end as at 80 to the baseplate 30 of the machinethe disposition of parts being such thatwhe'n'notension is placed on the cutter member 76. to: oscillate it about itspivot '75, the cutting edge '77 will lie immediately above the free end.of the wire tie which is subsee quently to be severed. The upper end ofthe cutter member '76 carries a roller 81 so positioned as to lie in theplane of the lever handle 62 so that a-cam 82 carried by said handlewill strikelsaid 3 and 7.

This cam 82 ismounted on thehandle at point near the lower end thereofwhen the handle is in raised position, so that when the handle is moveddownwardly, to tension the wire, the

cam 82 will be moved upwardly and during this,

movement the cam will; due to its inclination,

cause the roller 81 to move the cutter member 76. about its pivot toraise the cutting edge-'1'! still further above the-tie wire, thismovement being aninoperative oscillation of the cutter. On the otherhand, when'the handle 62 is raised, the cam, 82 will movedownwardly, andin this directional movement the opposite face of thecam will cause theroller 81 to move the cutter member oppo-;

sitely about its pivot so that the cutting edge will cause of the'notch78. r

'In operation, thetie wire is inserted inithe. well known manner throughthe several mouth,

roller and oscillate. the cuttermember, see Figs,

portionsihereinbefore mentioned and the extreme end of this wire ispushed axially'against the trip plate 48, thereby moving, said plateagainst the tension. of the light springs 52 and releasing the tooth 47of the dog 39 to permit oscillation of said dog to bring. its serratedsurface into gripping position on the end of the wire, forcing said wireagainst the surface of the anvil 38. It is to be observed that thisanvil surface is inclined downwardly in anoutward direction, so that thepressure of the dog 39 will cause a slight downward bend of the held endof the wire. This provides a set of said end which, after the knot istwisted and released, causes the end to be depressed below the uppersurface of the knot so that said end cannot .tear-or injure superposedpackages nor the hands of those moving the tied package.

; With the end of the wire thus secured by the dog 39, the bight 86lying in the innermost extremity of the twister pinion slot is passed tothe edge of the box, thence downwardly and under the box, thenceupwardly on the other side, and thence over the top of the box as bight87, see Figs. 1 to 4, and inserted in said various mouth portions andtwister pinion, with the extreme 'free end of the wire, indicated at 88,passed between the tensioning dog 69 and the lug 68 and thence loopedaround the post '71 of said dog. It will, of course, be understood thatduring the placement of the wire tie around the box,

both handles 8 and 62 will be in raised position,

as seen in Fig. 1.

The handle 62 is then moved downwardly about its pivot 61, which causesan outward swing of the tensioning lever 65, causing the dog 69 to gripmore tightly the free end 88 of the wire, and to. transmit theincreasing tension axially throughout the wire tie about the box, as iswell understood. When the handle 62 has reached the lowermost extremityof its stroke as indicated in Fig. 3, the wire will have been greatlytensioned, both bights forced to the inner extremities of the slotsprovided therefor in the side walls and the twister pinion, and the knotvvis then ready to be formed.

The handle 8 is then depressed or moved downwardly which actuates thetwister pinion through the intermediate gears 6 and 2, and since theslots of the mouth portions of the side plates 35 and 85, as well as theslot 18 of the twister pinion are of a dimension only slightly greaterthan the diameter of each bight of the tie wire, the two bights will bemaintained in parallel untwisted relationship at said plates and at themiddle portion of the twister pinion. The two bights betweentheseportions, however, will be twisted together with the ultimate formationof the knot shown in Fig. 13.

With particular reference to Figs. 1 and 3, it will be seen that thereis provided a screw 90,

' workable into and out of a portion of thecasing 1, for limiting theupward throw of the handle 8. In other words, this screw is moved intoor out of the casting of the casing and ultimately secured in thatposition which, when the handle 8 is thereagainst, will insure aregistration of the slot of the twister pinion with the slots of theside plates 35 and 85, A similar screw 97, co-

operable with the lug 98 formed on said handle,.

is provided for insuring similar registration at the lowermost throw ofsaid handle, thereby permitting discharge of the twisted knot. Hence, atthe. end of the tensioning and twistingoperations, both handles will bedown, and when the tensioning handle is raised, the free endof the wire88 will be severed from the knot.

tips the entire machine forward by means of the elevated tensioninghandle, thereby releasing the. knotted tie from the machine because ofthe regIstration of slotways. As hereinbefore stated, this machine isprovided with a base plate 30 extending under all-v from moving readilyover the upper surface of. the box or package andhence an important feature of this invention lies in the provision of means to permit movementof the machine in a direction axial of the tie wire during thetensioning and twisting operation, whereby the tension created by themachine on the tie wire. may be distributed more equally in both bights86 and 87 of the tie.

To this end the device is provided with a package or box contact plate91 wholly underlying the base plate 30, said contact plate provided atintervals with teeth or other projections, or otherwise suitableroughened, to cause agripping between said plate and the surface of thebox. The extreme rear edge of the contact plate 91 is turned upwardlyand over the base plate. 30 as indicated at 92 in Fig. 8, and theopposite or forward edge of the contact plate is provided at suitableintervals with horizontally elongated slots 93 to receive therethroughheaded bolts 94 threaded into the correspondingly upwardly rolledforward edge portion of the base plate 30.

Suitable anti-friction rollers 95 are disposed between the machineproper and the upper ,sur-,

face of the contact plate 91, said rollers being shown in Figs. 1 and 5and retained in position as by counter sinking in the bottom wall 96 ofthe casting forming the casing 1, these rollers being provided atsuitable spaced intervals. For convenience the casing 1 may be made intwo or more parts, there being shown in Figs. 8 and 9 a constructionproviding a front cover portion 99 secured as by the bolts 100 to themain body portion of the casing to permit ready access to the variousmoving parts. Preferably the joint between this cover portion 99 and themain portion of the casting is formed in an axial plane of the gearshaft 3 so that each of said por-, tions will. constitute a half-bearingfor said shaft.

From the foregoing disclosure it will therefore be seen that by thisinvention there is provided a machine for tying the ends of a wirepassed for example around a box, the tie being in the nature i of atwisted knot. The device is provided with means for tensioning one bightof the wire, as well as a pinion adapted to twist the, parallel bightsof the wire in the machine to formthe opposite directions on oppositesides offthe ma chine.

In addition the tensioningllever 62is operable in one directionIto'tension the wire and when operated in the opposite directionit actuatesthe cutter '76 to sever the end of the twisted wire. During thetensioning operation, the machine is permitted a rolling movement overthe under,-

most plate 91 which is provided on its undersur-i,

face with box engaging means in the natureiof With the twisting handle.3 still down, the operator then projections .or the like. Lastly thetensioning lever 62. is utilized in its raised position and afterthe'knot is tied, to tip or roll the entire frame of the machine forwardover the upwardly curved.

bottom edge of the device to permit the ejection of the twisted knotfrom the machine.

The clamping means for the tie wire comprises the dog 39 which ispivoted and provided with a tooth 47 -as well as a laterally extendingarm 56 sothalt'when the pin carried by the lever 8 for actuating thetwister pinion, is moved arcuately; said pin will strike said arm andoscillate the dog to' release the same from the endof the tie wire, andin this movement the tooth 47 will s'nap over the upper edge of theyieldable plate 48 and hold the dog in released position until it istripped by the next inserted wire.

It is obvious that those skilled in the art may vary the details ofconstruction as well as arrangements of parts without departing from thespirit of the invention, and therefore it is not desired'to be limitedto the foregoing except as'may be required by the claims.
